Field Emission from As-Grown and Ion-Beam-Sharpened Diamond Particles Deposited on Silicon Tips
Ion-beam bombardment/rnilling was used for sharpening of diamond particles deposited on ends of silicon tips. Radii curvature of diamond coating down to about 20 nm have been formed in such a way. Field emission experiments with sharpened diamond coated emitters have shown that the ion beam treatment effects a considerable shift of current-voltage characteristics of in the lower voltage region.
متن کاملDiamond vacuum field emission devices
This article reports the development of (a) vertical and (b) lateral diamond vacuum field emission devices with excellent field emission characteristics. These diamond field emission devices, diode and triode, were fabricated using a self-aligning gate formation technique from silicon-on-insulator wafers using conventional siliconmicropatterning and etching techniques. High emission current N0....
متن کاملEmission of neutral Mg from single crystal MgO during abrasion with diamond
We report observations of atomic, neutral Mg emitted from single crystal MgO during abrasion with a diamond stylus. These emissions take the form of bursts, where the onset of each burst coincides with a slip event often associated with the passage of the stylus over a cleavage step. After the onset, the emission intensity grows gradually to a peak, then drops sharply. Similar bursts of neutral...
متن کاملSingle Crystal Diamond Schottky Photodiode
Thanks to its extreme optical and electronic properties, diamond appears to be a promising semiconducting material for photon detection. Its wide band-gap, 5.5 eV, results in a very low leakage current and its electronic properties as high carrier mobility allow fast time response (J. E. Field, 1979). Besides, it has a large breakdown electric field (∼10 V/┤m), a low dielectric constant (i.e. l...
متن کاملEnhanced Field Emission from Diamond Coated Molybdenum Emitters
The field emission characteristics of individual Mo emitters were measured before and after diamond deposition, as well as before and after annealing. After coating without annealing, the emission current increased dramatically. Subsequent annealing resulted in further increases in emission and improved current stability. After coating, the energy distribution of the emitted electrons was found...
